Abstract :Self-Compacting concrete insert ignore into journalissuearticles values(SCC); is one of the most important technological developments in the construction material. Its use has increased significantly in recent years in the construction industry due to its high properties. though, the performance of fire-affected elements made of SCC mixture is primarily unknown. In this work, beams were produced of insert ignore into journalissuearticles values(SCC); in laboratory, and exposed to external fire at several reference time insert ignore into journalissuearticles values(30/60/90/120);min with two methods of cooling insert ignore into journalissuearticles values(subjectively, water);, where three levels of response were selected and evaluated insert ignore into journalissuearticles values(thermal transferring progress, Spalling, surface microstructure);, the results revealed that the damaged in the service loaded beam is interesting, corresponds to the characteristics of the cracks formed in the concrete section on bending zone which was photographically documented, and the progress of thermal transferring has a large values during insert ignore into journalissuearticles values(5-20); min in heating stage, and takes varies values insert ignore into journalissuearticles values(10-30%); at beam height where the curve been closer to linear.
